Help with DHCP Heartbeat

To those smarter than me,

 

I need help setting guarddog to allow a failover communication between 2 DHCP servers.  Both servers are identical and are running Red Hat Enterprise Linux.  I have tried several zone type setups but to no avail.

 

When initializing the failover it tests the other system with a heartbeat.  Communications are via port 647 and 16000 via the software manager for ipcommander.  If guarddog is running it fails, if I disable guarddog and enable the firewall within the OS, it works just fine.

 

Please offer help in step-by-step format as I am not a Linux professional.

 

Thank you in advance for your support.

 

Kelly

Adding new rules

Guess guarddog is running. What if i manually add a rule to iptables?
When I run guarddog and apply something it will erase the rule I done?
If I reboot, I will have to add  this rule manually again? Or guarddog
knows it and loaded when i ran it? In case guarddog saved the rule and
I don't want the rule anymore, how should I proceed?

Also, I allowed bitorrent internet/local local/internet and it doesn't
work, anyone having the same problem?

Guarddog edits the file /etc/rc.firewall.  It does not run all the time.  
Guarddog uses its own syntax within the rc.firewall file so if you stay 
within that syntax you will be fine.

You can do things like start guarddog, create a firewall, save it and close 
guarddog.  cp it to a different file name.  Then open guarddog and modify the 
firewall rule as you wish.  Save the new rule.  Now you can use cron scripts 
to switch between these two rules just by renaming the rules and then 
running /etc/rc.firewall (just be sure of permissions and ownership)

Trying to stop sounds when applying on Guarddog

Hi folks. First time on the list.

Everytime I click on apply in Guarddog, I get a blast of sound. I've tried, 
but can't find where to disable this. I use KDE, and system notifications are 
disabled, and also looked in Gnomes control centre to disable the sound, as 
Guarddog isn't a KDE app, but no joy.

I've used Guarddog, and Guidedog for 3 or 4 years, and am trying to resolve 
the odd problem here and there on my 2 machines.

Any help really appreciated in being able to disable the sounds.

Nigel.
